Using Function modules in BSP - Operations on Service Orders

Question

Hi,
We are creating a custom BSP application for scheduling resources and updating appointments for resource personnel.
The process is as follows:
From the list of Service Orders with some product added as line item, with status OPEN, the user selects a SO and makes an online payment.
Returning from the site, the Status of the Service order is changes to Released. Following this, the available resource is assigned to the Service order and the appointment details are populated in the Service Order. Subsequently, another line item of the Service order is set to Released.
We are using the following function modules in the order as given below:
To set status of a line item to Released
1)     CRM_ORDER_INITIALIZE
2)     CRM_STATUS_SET_INTERN_OW
3)     CRM_STATUS_SAVE_OW
4)     COMMIT WORK
To assign a resource to the Service Order
1)     WFD_RES_GET_AVAIL
2)     CRM_ORDER_INITIALIZE
3)     WFDS_GET_ASSIGNMENT_TO_SO_ITEM
4)     CRM_ORDER_INITIALIZE
5)     WFDS_CRM_SRV_ASSIGNMENT_MODIFY
6)     WFDS_SAVE
7)     WFD_TRANSACTION_COMMI
To update the assignment dates in Service Order
1)     CRM_ORDER_DEQUEUE
2)     CRM_ORDER_INITIALIZE
3)     CRM_ORDER_INIT_OW
4)     CRM_ORDER_MAINTAIN
5)     CRM_ORDER_SAVE
6)     BAPI_TRANSACTION_COMMIT
To set status of a second line item to Released
1)     CRM_ORDER_INITIALIZE
2)     CRM_STATUS_SET_INTERN_OW
3)     CRM_STATUS_SAVE_OW
4)     COMMIT WORK
Using these FM’s in a report program or even in Debug mode works fine, except in the BSP’s where the behavior is random.
The issue that we are facing:
1)     Calling the Function modules sequentially, it takes time to update the order after execution of a BAPI/RFC and at times the order gets locked although we are using the Function Module CRM_ORDER_DEQUEUE after a logical block, and the Service Order is un-available for subsequent actions
2)     At times, the Steps get executed correctly
3)     At times the Steps get executed correctly after adding certain delay after each logical block of steps, but at times the time is not enough for the order to get updated.
Can someone help us solve this un-predictable behavior?
If someone has previously worked on such a requirement, please provide inputs on the scenario.
Also, please let me know if there is a fail-proof procedure to ensure that the steps get executed completely and also if there is a need to use alternative BAPI’s in a specific order.
Thanks,

I am afraid you would have :
- to copy the standard FM 'MS_EXCEL_OLE_STANDARD_DATA' (it is wrapped up into EXCEL_OLE_STANDARD_DAT)
- to comment this line in this newly created FM
  SET PROPERTY OF obj_ex_app 'Visible' = 1.
- to call your own 'ZMS_EXCEL_OLE_STANDARD_DATA'
That should do the trick.
